12.3.1.7 Transmit Interrupt Register (TIReg)
The Transmit Interrupt Register has the interrupt events. If an event occurs whose interrupt
is enabled by setting the corresponding mask bit in the Transmit Interrupt Mask Register, it
causes an interrupt. This register is automatically cleared to zero after being read. Upon the
completion of reset, this register’s value is 0x0000_0000.
